# How To Do Orthogonal Projection

**In addition how do you prove two vectors are perpendicular.**

**How to do orthogonal projection**.
Video describes the theory of projection and basics of orthographic projection.
Suppose CTCb 0 for some b.
To nd the matrix of the orthogonal projection ontoV the way werst discussed takes three steps.

Thus CTC is invertible. Let C be a matrix with linearly independent columns. When has an inner product and is complete ie.

Suppose now we want find the projection matrix from the base B to the canonical C. We want to prove that CTC has independent columns. A plane is placed in the following two Methods.

In Euclidean space two vectors are orthogonal if and only if their dot product is zero ie. For drawing Orthographic Projection different planes are placed in a particular order. BTCTCb CbTCb Cb Cb Cb 2 0.

In this method two principal planes are kept perpendicular to. Then a specific view is drawn through every plane. Such that.

Definition of an orthogonal projection. Lets consider the projection wp of w in the basis B is given by. When is a Hilbert space the concept of orthogonality can be used.
